Displaying only lines that start with or contain -keyword-browsing

I’m doing heavy work on a txt file that stores a lot of data. All elements in the file have the same attributes. For example “Name=(string)”, next line “InternalName=(string)”, then on the next element, Name= and InternalName= appear again with different values. I’d like to only display specific lines, some starting with “Name=”, for example, so I can hide the rest of the file and avoid a ton of scrolling down. Is this possible at all?
